About this item
- Intensive Repair for Over-Processed Hair: Formulated with concentrated keratin proteins, this serum works deep inside the hair shaft to restore resilience and strength to strands weakened by bleaching, colouring, perming or constant straightening. By rebuilding internal bonds and sealing the cuticle, it reduces breakage, prevents further damage, and leaves hair healthier, smoother and more resistant to daily stressors. With regular use, hair regains its natural shine, elasticity and soft, touchable feel that lasts wash after wash.
- Advanced Frizz & Humidity Protection: Struggling with uncontrollable frizz and flyaways? This professional-quality serum acts as a smoothing barrier against external humidity, keeping hair polished, sleek and manageable even in damp weather conditions. Unlike heavy oils, the lightweight formula delivers a silky finish without greasiness, making it ideal for everyday styling. The result is a long-lasting smoothness that enhances both naturally straight hair and blow-dried styles, while leaving your hair with a luxurious, salon-like shine.
- Thermal & Styling Shield for Healthier Hair: Daily heat styling can cause irreversible damage, but this serum doubles as a protective layer against high temperatures from blow dryers, curling irons and flat irons. The keratin infusion helps prevent moisture loss and split ends, while ensuring strands remain flexible and nourished during every styling session. Use before straightening or curling to enjoy smooth, frizz-free results with less breakage, and maintain a glossy finish that holds its shape throughout the day.
- Shine Enhancing Serum for Sleek Finish: Perfect for dull, lifeless or coarse hair, the serum instantly revives strands with a luminous glow that reflects light for a radiant, healthy look. It smooths rough cuticles, enhances the appearance of straight hairstyles, and provides that silky “just left the salon” effect. Even a small amount is enough to transform dry ends into silky tips, keeping your hair glossy, soft and easy to comb through without the heaviness of traditional oils.
- Lightweight, Easy Application for All Hair Types: Designed for men and women with straight, curly, wavy or textured hair, this non-greasy serum absorbs quickly and leaves no sticky residue. Simply apply a few drops to damp hair before blow-drying for protection, or smooth over dry hair as a finishing touch to reduce flyaways and boost shine. Suitable for daily use, it nourishes without weighing hair down, making it perfect for fine, thin, thick or chemically treated hair that needs both hydration and a smooth, polished finish.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
